Solution Overview
Problem
Existing battery measurement systems require significant human effort for aligning battery terminals, which hampers efficient performance measurement of multiple batteries.
Innovation Solution
A battery measurement jig with sliding battery terminal connection portions and elastic supports, allowing for automatic alignment and connection of battery terminals on a flat bar, along with a temperature measurement jig using thermistors with elastic positioning, reduces the need for manual positioning adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batteries are arranged side by side for performance measurement, then measurement capability is improved, but human effort for terminal alignment increases
Solution Approach 1:
The battery terminal connection portion base automatically adjusts its position on the flat bar through the clearance mechanism, allowing the battery terminals to self-align with the probes without requiring manual intervention. The elastic body provides automatic positioning force that compensates for variations in battery terminal positions.
Solution Approach 2:
The battery terminal connection portion base is designed to be movable in the direction perpendicular to the battery terminal direction through the clearance between the base and flat bar. This dynamic adjustment capability allows the system to adapt to position variations and achieve proper alignment automatically.
2Manufacturing precision
If manual alignment of battery terminals is performed, then connection accuracy is improved, but measurement time increases
Solution Approach 1:
The battery terminal connection portions are pre-positioned on the flat bar with the ability to adjust within clearance ranges. The elastic bodies are pre-loaded to provide automatic positioning force, so that when batteries are placed, the terminals automatically align without requiring time-consuming manual adjustment.
Solution Approach 2:
The system performs automatic alignment through the interaction between the movable battery terminal connection portion base and the fixed probes on the flat bar. The clearance mechanism and elastic bodies work together to self-correct positioning errors, eliminating the need for manual alignment operations.
